Not all colored diamonds are HPHT processed. Artificial treatments--like color coating--can be used and are sometimes mistakenly confused with HPHT. Only Suncrest offers permanent, fully saturated color diamonds.

Judging Quality

Diamonds that qualify for High Pressure High Temperature (HPHT) processing are rare.

Only 2% of the diamonds available on the market today will meet Suncrest's high standards for color change. Specialized understanding
and proprietary technology are required to identify and process each Suncrest diamond. Unlike other color diamond suppliers, Suncrest can deliver beautiful color diamonds in large sizes,
0.10 - 3 carats and larger.

What is HPHT?

High Pressure High Temperature (HPHT) diamonds can be man-made or natural diamonds that have been enhanced. These diamonds are high quality and have a special chemistry that allows for color change.

By using advanced HPHT technology, Suncrest Diamonds can heat treat a natural diamond (similar to rubies and sapphires) to change the diamond's color. The Suncrest process replicates the geological pressure and temperatures (approx. 5000°F) that occur in the earth to expose the true nature of each diamond––thus finishing the process the earth began.
